Breast carcinoma is one type of cancer that is treated with cisplatin, a chemotherapy drug. By using liposomal nanocarriers, this study seeks to increase the therapeutic efficiency of cisplatin. Method: The zeta potential, particle size, and drug-release characteristics of nanoliposomal cisplatin were evaluated after it had been synthesized using the reverse phase evaporation technique. The cytotoxicity rate of nanoliposomal cisplatin was then assessed using the T-47D breast cancer cell line. Results: This study’s liposomal nanoparticles (NPs) had a zeta potential of -24.9 mV and a particle size of 342.3 nm. 3.51% and 79.6%, respectively, were found to be the drug loading level and amount of encapsulated drug. A significant improvement over the free drug was seen in this nanoliposome’s cytotoxic effect on the T-47D breast cancer cell line (P<0.05). Conclusion: According to what we have discovered, cisplatin liposomal nanocarriers may prove to be a cutting-edge chemotherapy treatment for breast cancer.","PeriodicalId":8848,"journal":{"name":"Asian Pacific Journal of Cancer Biology","volume":"13 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-07-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76091305","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Background: Colorectal cancer (CRC) is third most common cancer with a high mortality. Many attempts have been made to raise overall survival of CRC patients. The immune system plays an important role in clearing the unhealthy cancer cells. Programmed death 1 (PD1) is a regulatory molecule which dampens the immune response when bound to one of its complementary ligands (PDL1). Its expression is related to the response of immunotherapy in CRC treatment which has been exploited in recent times. However, its prognostic value is still controversial, and the distribution of PD-L1 on tumour Cells or Immune Cells has not been comprehensively analysed. Method: A total of 30 patients diagnosed with CRCs were included who underwent surgical intervention. Cases who took preoperative neoadjuvant chemotherapy or radiotherapy were excluded. IHC analyses of PDL1 was done and was correlated with tumour budding and Tumour Infiltrating Lymphocytes (TILs) and statistical significance was assessed. Results: 11 cases showed low bud count at the invasive front out of which only 3 cases showed PDL1 positivity. The rest 19 cases had high bud count out of which 18 were PDL 1 positive. This difference was highly significant (p = 0.002). In Low Bud / High TILs, 75% cases showed no PDL1 expression in tumour cells, whereas 62.5% cases showed PDL1 positivity in TILs whereas in High Bud / Low TILs group, all the cases (100%) showed PDL1 expression in tumour cells whereas only 75% cases showed PDL1 positivity in TILs, again being statistically significant (p <0.001). Conclusion: This study showed an inverse correlation between PDL1 in tumour buds and immune cells, thus emphasising the role of tumour microenvironment. Our study reiterates the fact that high expression of PDL1 in tumour cells suppresses antitumor response whereas its high expression in TILS correlates with a better prognosis.","PeriodicalId":8848,"journal":{"name":"Asian Pacific Journal of Cancer Biology","volume":"96 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-07-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76236779","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A panel of markers has been recommended by the International Mesothelioma Interest Group (IMIG) guideline to differentiate epithelioid mesothelioma from lung adenocarcinoma and SCC. However, the use of novel highly specific immunohistochemical (IHC) markers is still required. Objectives: This study aimed to evaluate glypican-1 (GPC1) expression in epithelioid mesothelioma, lung adenocarcinoma, and SCC, correlating its expression with some known clinicopathological parameters to clarify its diagnostic and prognostic value.Methods: This study included seventy specimens designated as 20 cases of pleural epithelioid mesothelioma, 30 cases of lung adenocarcinoma, and 20 cases of lung SCC. GPC1 expression was evaluated using immunohistochemistry (IHC). The data was analyzed statistically by SPSS software 25. GPC1 expression was correlated to different clinicopathologic data using Chi-square test. The study was conducted according to local Ethical Committee regulations. Results: This study detected positive GPC1 reactivity in all cases (100%) of pleural mesothelioma and lung SCC, in which increased GPC1 expression was correlated to large-sized, high grade, advanced stage tumors, and the presence of lymph node metastasis (LNM). In contrast, GPC1 expression was absent in about 93% of lung adenocarcinoma cases, and only 2 cases exhibited weak focal expression.

The purpose of this study is to assess the frequencies of ALK, ROS1 and their association with EGFR fusion gene mutations in a spectrum of lung tumours. Materials and methods: A total of 202 cases of lung tumours reported at our Center for Oncopathology from September 1st 2020 to 31st August 2021, were retrospectively analyzed for ALK, ROS1 and EGFR fusion genes based on Immunohistochemistry (IHC) and Multiplex PCR findings. ALK was tested using D5F3 clone, and ROS1 was analyzed using Cell Signalling’s D4D6 clone on the Ventana immunohistochemistry platform. EGFR status was analyzed using EGFR mutation test V2 real-time multiplex PCR assay on Roche Cobas Z480. Results: 202 biopsy samples and cellblocks of fluid aspirates were analyzed. 175/202 were histologically and immunologically proved as Non-small cell lung carcinoma (Primary pulmonary adenocarcinoma) and its metastases. 09/199 (5.23%) were Positive for ALK IHC and 03/199 (1.74%) cases had equivocal results. 06/179 (3.85%) cases were Positive for ROS1 IHC and 03/179 (1.92%) cases had equivocal results. Other histo-morphological diagnoses i.e., adenosquamous, squamous, small cell, mucinous carcinoma etc (27 cases) were all ALK and ROS1 Negative. 188/202 tumours were analyzed for EGFR mutation status, which showed 70/188 (37.23%) had specific EGFR mutations. 118/188 (62.76%) cases were EGFR wildtype. Conclusion: We observed that age related incidence of EGFR mutations was highest in elderly females, of 61 to 70 years. ALK gene mutations occurred in 6.03% and ROS1 gene mutations occurred in 5.02% of lung tumours and their metastases. EGFR-mutations were associated with ROS1 mutated lung adenocarcinomas.

We aim to present our data regarding the prevalence and expression pattern of PD-L1 across various tumors based on site and histology and compare them with those of the reported literature. Material and Methods: A retrospective study of 301 cases of various tumors at different sites was done for PD-L1 IHC using the 22С3 pharmDx assay on the recommended platform.Results: Out of 237 non small cell lung carcinoma cases, 14.7% were squamous and 85.2% were of nonsquamous histotype, with adenocarcinomas comprising the majority (82.2%). Fifty-seven percent of non small cell lung carcinoma was PD-L1 positive, 28.6% showed high expression. Sixty percent of the squamous and 56.4% of the non-squamous histotypes showed positive immunoexpression. Amongst non-squamous types, 56.4% of adenocarcinomas and 66.6% of sarcomatoid carcinomas were positive. At metastatic sites, 54.3% of on small cell lung carcinoma were positive. In head and neck squamous cell carcinoma, the majority (10/11) of cases were from the oral cavity; 81.8% of total cases were positive, 27.2% were strong expressors. For other sites, the number of cases showing PD-L1 immunopositivity is as follows: oesophageal squamous cell carcinoma (2/6), gastric adenocarcinoma (2/6), triple negative breast carcinoma (0/3), urothelial carcinoma (2/5), gall bladder (2/5), pancreatico-biliary (2/11), and colorectal (2/17) adenocarcinomas.

It is preventable through early detection of persistent high-risk HPV infection, which is a critical promoter. Screening methods have evolved from pap smear cytology to HPV-DNA testing and currently to co-testing, but these methods still result in false positives and high colposcopy referrals. p16/Ki-67 dual immunostaining was proposed as a biomarker for cervical cancer triage due to its ability to detect HPV-mediated neoplastic transformation. The aim of the study was to evaluate the sensitivity and specificity of this dual staining method through a review and meta-analysis of published data.Material and Methods: The search was based on PRISMA guidelines using specific MeSH terms and keywords. The search was limited to publications that compared p16/Ki-67 dual immunostaining to Pap cytology and/or high-risk HPV-DNA and included colposcopy biopsy results as the diagnostic standard. The study focused on diagnostic performance outcomes such as sensitivity, specificity, and diagnostic odds ratio. To be eligible for meta-analysis, a publication must report the diagnostic performance at predicting CIN2+. Results: A total of 24 studies were included in the review and 21,450 samples were used for dual immunostaining. The results showed that dual immunostaining was significantly more sensitive than pap cytology (75.9% compared to 71.1%) and had a higher specificity (79.7% compared to 64.3% for pap cytology and 48.9% for HPV-DNA). A meta-analysis showed that dual immunostaining had a higher pooled diagnostic odds-ratio compared to pap cytology and HPV-DNA, indicating a better test power. Conclusions: The study suggested that dual immunostaining is a better approach for detecting HPV-induced cervical cancer compared to traditional screening methods. The authors suggest that despite its reduced sensitivity, dual immunostaining should be considered as a promising alternative, especially in large-scale testing.","PeriodicalId":8848,"journal":{"name":"Asian Pacific Journal of Cancer Biology","volume":"4 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-04-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82080695","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
